Self-cleaning test fixtures
This article is originally published at https://www.tidyverse.org/blog/Adapted from an internal presentation to the tidyverse team, which tells you something about the target reader. The primary audience for this post is R programmers and, especially, package developers. The problems identified and solved here are pretty niche! People who are mostly interested in R as a data analysis tool may not have direct use for this material. But the post offers something for anyone curious about the hazards of side effects and the various ways we can leave the world as you found it.
